Hello,
I think there is a bug in the V1.70: after a data transfer there is a reset of the compartments saturation.
Several times I didn't understood why there was no saturation left after a dive but yesterday I noticed that there was still some saturation after the dives done the day before but once I down loaded the curves to my laptop, saturation was reseted. I think this always happened that way but I'm not sure of it. I'll check if this still happen tomorrow and I'll keep you informed.
I think this should not occur because even if you transfer you profiles to your computer, you want your computer to calculate the residual saturation for the next dives.
I wouldn't download any profiles until I know I'll be fully desaturated for the next dive.
Thank you!
François
